High blood pressure or hypertension can be an acute problem. The heart muscle enlarges and can become weaker over time. Hypertension is one of the risk factors for strokes, he…art attacks, heart failure, and renal failure. Low blood pressure or hypotension can cause decreased blood supply to the brain and shock. Other causes of low blood pressure or hemorrhage, sepsis, and toxins.

I always thought, being a railroad buff and familiar with PSI, that it was in Pounds per square inch. Some Path cars ran a standing pressure in the brake system- Main over equ…alizing, of ll0/70, exactly l0 pounds below the Human norms, the joke was the M-58 cars are a little anemic ( this was compressed air, to operate the brakes) Alas it is ( Blood pressure) actually in MM/Mercury ( Mercury column gauges are still in use, in some quarters) and NOT PSI. People still say (pounds) as it is a sort of flag of convenience, like the confusion of (Two Blocked) with Half Mast in reference to flag usage. Two Blocked originally meant the Flag was ALL the way up- touching the blocks of the pulleys. By some popular misunderstanding- as with the Blood Pressure, as Half is l/2 l over Two- somehow people will say ( the Flag was Two-Blocked for President Kennedy) for example, when they mean Half-Mast. so it goes.

I don't really know what you're getting at with this question. Blood pressure is measured with three numbers, systolic, diastolic, and pulse rate. Systolic pressure measures t…he blood being pumped through the heart when it contracts, where diastolic measures the relaxation of the heart muscle to allow blood to fill the chambers. Puls rate is how many contract-relax cycles happen in one minute. Hope this helps...

Blood pressure is is sometimes called arterial blood pressure. It is caused by circulating blood on the walls of arteries. When the heart beats, it does not have a constant pr…essure. It rests slightly in between beats. There is a maximum called systolic and a minimum called diastolic. The pressure is measured in the upper arm at the brachial artery. The BP is expressed in systolic pressure over diastolic pressure in millimeters of mercury (mmHg) and normal blood pressure for an adult is 120/80.

The BP is expressed in systolic pressure over diastolic pressure in millimeters of mercury (mmHg) and normal blood pressure for an adult is 120/80. BP varies according to age, stress, drugs, disease. BP can be measured using palpitation in emergency situations. This only gives a rough estimate of systolic pressure. It can be used with the carotid, the femoral, or radial pulse.

Blood pressure is measured in millimeters of mercury, or mmHg. The top number of the blood pressure is known as the systolic number, and the bottom number is known as the …diastolic pressure. i.e. 120/80 mmHg is how the blood pressure is measured and recorded.

I suffer from high blood pressure at 42yrs old and was diagnosed around 4yrs ago. The medication my doctor prescribed is Norvasc, 20mg once daily before bed and it seems t…o be helping. According to my doctor and his P.A. the normal average blood pressure is 120/80. I tend to average aroung 160/120. According to them that isn't bad for someone with my lineage and condition. Thank God my cholesterol is normal. There's a history of heart disease on my mother's side.
